Location: Palo Alto, CA

 

We are looking for an experienced Audio DSP Engineer to join our In-Vehicle Infotainment (IVI) audio development team for electric vehicle platforms. The role will focus on real-time audio signal processing, particularly voice communication / ECNR and audio post-processing.

This is a hands-on engineering role. The ideal candidate should be comfortable developing, integrating, debugging, tuning, and validating audio algorithms on an embedded production platform.

 

Responsibilities

• Development of audio processing stack: Drive the implementation and optimization of the infotainment audio software stack.
• Develop and integrate voice communication and voice recognition solutions for IVI (In-vehicle infotainment) platforms.
• Work closely with HW engineers and the system integration team to ensure tight integration and that the audio stack meets high-quality standards.
• Work closely with QA team to perform comprehensive testing, debugging, and validation.

 

Required Qualifications

• Audio Digital Signal Processing (DSP): Strong hands-on development experience with speech and microphone-array signal processing algorithms. Experience with several of the following components is expected:
• Acoustic Echo Cancellation (AEC)
• Adaptive Beamforming: MVDR or similar techniques
• Noise Reduction (NR)
• Residual Echo Suppression (RES)
• Voice Activity Detection (VAD)
• Automatic Gain Control (AGC)
• Wind noise reduction
• Directional of Arrival (DoA) estimation
• Speech enhancement
• Audio Post-Processing: Hands-on experience developing or integrating real-time audio playback and post-processing pipelines, including:
• Audio mixing / routing
• Volume / Gain control
• Mute / ducking
• Channel mapping
• Equalization
• Audio filtering
• Sample rate conversion, etc.
• ALSA / Linux Audio: Strong understanding of Linux audio architecture, particularly ALSA
• Real-time Audio SW Development experience: Strong C/C++ software development experience with real-time audio processing systems.

 

Preferred Qualifications

• Commercialization experience: Voice communication and/or Voice recognition features

• Automotive / IVI Experience – Strong Plus: Experience developing audio systems for automotive or IVI platforms is highly desirable.
• Hands-on experience with DSP Concepts Audio Weaver (AWE) is highly desirable.
• Experience with acoustic measurement, tuning, and validation equipment and tools: HATS, HEAD acoustics, Audio Precision
• Experience with Python and MATLAB also highly desirable

 

Salary Range

• $160,000 - 175,000
• The actual salary offered is dependent on various factors including, but not limited to, location, the candidate’s combination of job-related knowledge, qualifications, skills, education, training, and experience
